The Ultimate Aquaculture Quiz

Seafood has been popular for centuries, but it should not be taken for granted. The demand for sea products is outweighing the number of organisms left in the sea. This is where aquaculture comes in. Take this quiz to see what you know about aquaculture, one of the fastest growing fish industries in the world.

Question 1 of 20

What is aquaculture?

fish farming

Aquaculture is the farming of fish in a controlled environment, in either freshwater or saltwater.

fish catching

fish hunting

Question 2 of 20

Since when have goldfish been cultivated using aquaculture techniques?

800 A.D

The Chinese have cultivated and domesticated goldfish since around 800 A.D. Goldfish cultivation spread to Europe and other eastern countries in around 1650 A.D. and it was only in the late 1800s that goldfish moved indoors.

1200 A.D.

1600 A.D.

Question 3 of 20

What important nutrient does fish provide?

magnesium

protein

Fish is one of the most important sources of protein. Many of the world's poorest populations depend on fish as a protein source.

carbohydrates

Question 4 of 20

What has happened to the demand for fish in recent times?

It has reduce.

It has doubled.

The demand for fish has doubled since the 1950s.

It has tripled.

Question 5 of 20

Why is the aquaculture industry booming?

due to its low costs

due to its simplicity

due to overfishing

Overfishing has lead to the scarcity of some species of fish, such as Atlantic salmon and Chilean sea bass. This has boosted the aquaculture industry, where these fish are bred under controlled conditions to meet the demand for fish products.

Question 6 of 20

What is the primary form of aquaculture?

fish farming

The primary form of aquaculture is fish farming. This is the process of cultivating fish in man-made tanks for commercial purposes.

farming of marine organisms

farming of algae

Question 7 of 20

What sort of water is used for mariculture?

pure water

chlorinated water

saltwater

Marine organisms are cultivated in mariculture using saltwater or seawater. This is done using enclosed portions of the ocean or tanks filled with ocean water. Finfish, shellfish and sea plants, such as seaweed, are cultivated using this method.

Question 8 of 20

Products for which other industry, besides fishing, are cultivated using mariculture?

cosmetic

Products cultivated in mariculture are used for cosmetics, fish meal and for jewelry, such as cultured pearls.

pharmaceutical

entertainment

Question 9 of 20

How is macroalgae commonly referred to?

seaweed

Most algae cultivated by algaculture is either microalgae or macroalgae. Macroalgae is commonly known as seaweed and can be difficult to grow due to its size and cultivation needs.

fish

coral

Question 10 of 20

Algae is usually cultivated in open-pond systems. What is the problem with these systems?

They are expensive.

They produce small yields of algae.

They are not temperature controlled.

Open-pond systems, such as pools, ponds and lakes, are popular because they are cheap and easy to build and they produce the highest yields of algae. However, algae farms grow best within a particular range of temperature and light, which cannot be controlled in open-pond systems.

Question 11 of 20

What type of algae crop is yielded in closed-pond systems?

large crops

a variety of species

Close-ponds allow for light and temperature monitoring enabling more species of algae to grow. However, since the ponds are usually smaller, less algae is yielded.

purer algae

Question 12 of 20

The U.S. government is investigating the use of algae for what?

fuel

Algae contains large amounts of lipid oil, which can be converted into biodiesel fuel. Algae grows very quickly, meaning it could be a renewable source of fuel.

IMTA systems are advanced systems of aquaculture, where waste products of one species become the food of another species. For example, shrimp and fish excrete phosphorous and ammonia, which is used by seaweed to grow. This makes IMTA systems both environmentally and economically sustainable.

because they are cheap to build

because they require little monitoring

Question 14 of 20

Toward the end of which century did North Americans begin to widely practice aquaculture?

1700

1800

1900

Aquaculture possibilities were explored in the U.S. and Canada from the mid 1800s. However, only it was only in the late 1900s that aquaculture became widely practiced in the U.S.

Question 15 of 20

Which of the following are important factors when choosing the right site for a fish farm?

salinity

Aquaculturist look for a site with the right conditions, including temperature, salinity and fertility. If these factors are right, organisms should be able to flourish.

amount of water

proximity to fish markets

Question 16 of 20

Which of the following is a feature considered before aquatic organisms are chosen for an aquaculture site?

the reproductive habits of the organism

Features of aquatic organisms that are considered for aquaculture are their reproductive habits, the requirement of eggs and larvae, the ability for the organism to adapt to crowded conditions and the feeding habits of the organism.

the size of the organism

the lifespan of the organism

Question 17 of 20

How do fish catch diseases?

by transfer through water

by rubbing against each other

Fish farms may become overcrowded, leading to a build up of fish waste that can pollute the water. As fish rub against each other or against the tank walls, they get scratched or cut, providing an opening for diseases and infections.
